Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a drawer lock device for a sorting box having a number of drawers for storing various specimens, various documents, various cards, various cassettes, and the like.

[0002]

[Prior art]

 Conventionally, for example, in a herbal medicine storage box having a large number of drawers, as a drawer lock device for preventing a drawer from popping out due to an earthquake, L-shaped stoppers are attached to both left and right ends of the box, and each drawer is attached to both stoppers. It is known to lock both ends of a cross bar that has been passed to the front and to prevent each drawer from jumping out by the cross bar.

However, in the above-mentioned conventional apparatus, there is a risk that the rungs may come off from the stoppers due to a severe earthquake, and in an organizing box having many drawers above and below, when goods are stored in or taken out from each drawer, In addition to the inconvenience of engaging and disengaging the crossbars in each of the many drawers, there were drawbacks that hurt the appearance.

[0004]

[Problems to be solved by the invention]

 The present invention maintains the lock of the drawer even during a severe earthquake, and can easily engage and disengage the lock even in a storage box with multiple drawers arranged in a row in a row with many drawers arranged side by side. It is an object to improve satisfactorily.

[0005]

[Means for Solving the Problems]

 In view of the above, the present invention provides an arrangement box having a plurality of upper and lower rows of drawers in which a number of drawers that can be pulled out in front are arranged in a row in a row, and a latch frame is not separated from the front of the arrangement box. And a plurality of latch rods corresponding to a plurality of upper and lower stages of the drawer group are fixed to the latch frame, and the latch rods of each stage are in front of all the drawers included in the horizontal drawer group. The latch frame is displaceable from a lock position at which each latch bar blocks the front surface of the row drawer group to an unlock position at least deviated from the lock position. A drawer lock device for a multi-drawer arrangement box, which has a vertical movement range and has a locking means for locking and unlocking a latch frame at the lock release position independently. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

【Example】

 The sorting box with multiple drawers (A) used in this example has the same size and shape as shown in FIG. Rows Boxes with drawers (a): A large number of boxes (a) are stacked one on top of the other with boxes (a) locked together with the drawers (1) of each box (a) facing in the same direction. The top plate (2) and the bottom plate (3) are connected to the upper and lower surfaces.

[0007] Side plates (B) and (B) are attached to the left and right side surfaces of the rearranging box (A), and the side plates (B) and (B) are attached to one side end thereof as shown in FIG. It has a guide groove (4) having a U-shaped cross section of a length that covers the entire height of the sorting box (A). These side plates (B) and (B) are connected to the guide grooves (4) and (4). Is vertically extended at a position where it protrudes forward from the front of the rearranging box (A), and the slots are opposed to each other. Then, as shown in FIG. ), And the latch frame (C) is slidably held in the guide grooves (4) and (4).

The latch frame (C) has a number of latch rods (7) corresponding to the number of the boxes (a)... In a rectangular frame (6) composed of left and right vertical frame members and upper and lower horizontal frame members. Are connected in the form of a horizontal rail at a center interval equal to the vertical center interval of the box (a), and each latch bar (7) is connected to all the drawers (1) stored in the box (a). It is the length facing the front of The left and right vertical frame members (6 ′) and (6 ′) are inserted into the guide grooves (4) and (4) of the latch frame (C) thus configured, and the rearranging box (A) is arranged as shown in FIG. And is slidably held up and down so that it cannot be separated from the front surface.

In this example, when the latch frame (C) is positioned at the lowest position in contact with the floor surface with respect to the sorting box (A) installed on the floor, each of the latch bars (7). a) Each row drawer (1) is in a lock position that blocks the front of the group, and when the latch frame (C) is slid upward as appropriate, each latch bar (7) comes off the lock position. The upper and lower adjacent boxes (a), (a) can be moved to an unlocked position (8) consisting of the front surface of the lower plate. The unlock position (8) of the uppermost box (a) includes the front surface of the top plate (2).

Means for locking each of the latch bars (7) of the latch frame (C) in the unlocked position is provided. A vertically long hole (9) is provided in the front side wall (4 ') of both side walls constituting the guide groove (4), and the width of the hole is changed from the long hole (9) as shown in FIG. Insert a locking screw (10) with a larger diameter seat (11) and screw it into the vertical frame member (6 ') with the latch frame (C) at the lowest position. When the rod (7) is in the locked position, the locking screw (10) is located at the lowermost end of the elongated hole (9) (the state shown in FIG. 3), and the latch frame (C) is raised to release each latch. When the bar (7) is in the unlocked position, the locking screw (10) reaches the uppermost end of the long hole (9), and when the screw (10) is turned there, the vertical frame member (6 ') Is pressed against the side wall (4 '), thereby holding the latch frame (C) in the unlocked position. (12) is a knob of the screw (10). Elongated holes (9) and screws (10) having the same structure are also provided on the guide groove side wall on the other side.

The above-mentioned locking means is not limited to the above example, but may be a member in which a locking pin is removably inserted into a hole of the vertical frame member of the latch frame from a hole in the guide groove side wall. A latch pin having a latch frame resiliently provided thereon, and the latch pin is resiliently latched in a hole of the latch frame vertical frame member, and various other types are used.

The operation of the above example will be described. In FIG. 1, each latch bar (7) is positioned in front of a row of drawers (1) of a group of boxes (a) in each stage to prevent each drawer from jumping forward. In this state, when the drawers (1) of each stage can be opened, first, the latch frame (C) is lifted, and the locking screws (10) and (10) are inserted into the slots (9) and (9). After moving the latch rods (7) to the unlock position (8) to the upper end, the locking screws (10) and (10) are tightened and the latch frame (C) is moved to that position. To hold. In this state, open and close the optional drawer (1) and take out and put in the object. When the work is completed, loosen the locking screws (10) and (10) and lower the latch frame (C) by its own weight. Each latch bar (7) moves to the lock position and locks the drawers (1) of each stage so that they cannot be pulled out.
